I recently purchased a ultraportable acer laptop called ASPIREone .
Its very got a small 8.9 inch screen weighs about 1 kg, and runs on intel atom processor, which is the entry level processor from intel , don't expect to run heavy applications, it might slow down the system, but its so wonderful to carry when you are travelling, and it comes cheaper than most multimedia mobile phones.
On the downside, It is quite tacky looking, don't expect great finish.Its a cheap laptop, more aimed towards the smaller towns or the busy travelling sales man.
So would recommend it to anyone, who want to travel, maybe bloggers who cannot afford not to jot down an inspiration or miss an opportunity to blog.
I purchased it for Rs17699 at eZone at powai, saw it retailing for Rs19699 at Vijay Sales, but do ask for discount on the black color.
